title: [Study on melamine migration rules in products of tripolycyanamide for food packaging].
abstract: OBJECTIVE
  To study the migration rules of melamine in products of tripolycyanamide for food packaging.
  
  
  METHODS
  With different stimulant solutions, temperatures exposure and long term use, the migration quantities of melamine in products of tripolycyanamide for food packaging into 3% acetic acid and 15% ethanol were measured by HPLC method.
  
  
  RESULTS
  The amounts of melamine migrated to 3% acetic acid was higher than those to 15% ethanol. Higher temperatures more amounts of melamine of products of tripolycyanamide were migrated. With the higher temperature exposure was done, the amount of melamine migration reached maximum in lower number of repeated exposures. After 10 times of migration tests, melamine still can be migrated but the amount was not high. The single maximum migration amount was 0. 0851 mg/dm2, and the value was approximately 1/59 of the SML regulated by EU regulations.
  
  
  CONCLUSIONS
  3% acetic acid is the most serious solvent. The higher the temperature, the greater the migration, and melamine still migrate after repeated use.
